In order to optimisation of laminates including woven fibers, Present study investigated the effect of Areal density on the tensile and flexural properties of this laminates. Due to the complexity of the equations governing woven fibers, the experimental method has been used to accurately compare the properties of laminates including fibers with densities of 200, 400 and 600 gsm. The laminates studied in this research have equal thickness and overall density and their difference is in the number and Areal density of the constituent layers. In order to reduce the impact of the manufacturing process and the uniformity of the quality of the parts, the vacuum injection method has been used. Research findings show that Areal density has a significant effect on the properties of laminates and by increasing it in a certain range, the properties of laminates improve. Also, increasing the surface density of a certain value due to the creation of cavities and reducing interlayer contact, has a negative effect on the properties of the laminates. laminates including woven fibers with a density of 400 gsm have higher properties than other laminates and also fibers with a density of 600 gsm have higher properties than laminates containing fibers containing 200 gsm.
